A ring element includes a convex, in particular rounded, surface element for arrangement on at least one axial end region of a winding section of an electric motor rotor. The surface element provides a minimum radius curvature for supporting an inner layer of a rotor winding on the winding head. An insulating lamination element for an electric motor rotor onto which a rotor winding is intended to be wound includes the ring element. An electric motor, in particular a universal motor, includes a rotor with a rotor winding having the ring element. An electric machine tool, in particular a handheld electric machine tool such as an angle grinder, a drill, a saw or the like, includes the electric motor.

The invention is based on a power tool with at least one handle () that comprises at least one grip part () that is firmly connected to a mounting part () via at least one elastic, vibration-damping element (), via which the grip part () is affixable to a housing (). It is proposed that the connection between the grip part () and the mounting part () is secured by means of the elastic element () via at least one movable retaining element ().

A self-closing water valve has a valve seat, a valve closing member cooperates with the valve seat so as to abut against and to be lifted from the valve seat, and an auxiliary valve coupled with the valve closing member for reducing operational forces during lifting of the valve closing member from the valve seat and therefore opening the valve.
